Conni bear, leg holds, snares and live traps all have their uses. Leg holds in a city are not a good idea.
Other than survival situations non live traps are not legal in colorado.
Like Wulf202 said.
"foot catching traps" or "leghold traps" are....with some exceptions....illegal in this state.
In a SHTF scenario, I wouldn't hesitate to use any of the ones I have.
Colo Rev Stat...
